Cole starting to deal a little bit now, and is also getting some help from the umpire with close calls -- two things that tend to run in tandem, and he's kind of established himself as that type of pitcher this season, which is just great to see. In earlier seasons, he would basically dominate with similar stuff, but would not get a lot of calls, which coupled with a slightly lowered ability to miss bats, led to way less strikeouts.
Now the strikeouts are pouring in and he's at bonafide ace status.
